To find the way to Muxía, head back along the road you came in on. At the cruceiro that marks the end of the beach stay on the road. It curves left at the cruceiro, and then curves right. Turn left (uphill) at the first second street, and follow that straight on to San Martiño. IF you stayed at any of the albergues in Finisterre that are at the upper part of town, ask them for directions because the route described above might take you somewhat out of the way.
